While PN subs will be deep further down in indian ocean for HVTs.

Also note, that PN's submarine fleet will be many times more advance than india's by 2030, that's just in next 4 years. Its the most lethal component of naval warfare. PN will have 11 modern AIP equipped subs while india's diesel subs are on average 30+ years old and all of them have submerged capacity of 1-2 days at most.

AIP keeps you quiet, sure. But at what speed? You’re creeping along at 3-4 knots. That’s the tradeoff.

Look at the Arabian Sea. When your U-boat cross a thermocline, a salinity boundary, the whole acoustic picture changes. Your U-boat also got machinery heat and other signatures in the water. The newer drifting sensors and multistatic setups can keep listening, collecting contacts and slowly tightening the area.

By sitting in the same area for too long is not exactly helping it either.
Then something happens and it needs to move. That's the bit the AIP fanboys never seem to talk about.

What'll happen if you need a burst of sprint? Your power demand suddenly jumps, lead acid batteries have to pick up the extra load, noise goes up and you're burning through the battery reserve. Keep doing that and those impressive endurance figures disappear pretty damn quickly. AIP is great when you're creeping along quietly. It doesn't give you unlimited power when you suddenly need to move.

And sooner or later you still have to snorkel. The other side doesn't need to put a P-8 over you every secs. Cheap unmanned systems can loiter for days, drop sonobuoys and just listen. They don't have to find you instantly. They just have to keep narrowing the box.

The crew can also get sucked into the endurance game. If the U-boat supposedly has weeks underwater, it's easy to get comfortable staying in the same patrol area longer than you otherwise would. Then one unexpected contact forces a rapid move and you'll be forced to burn through the battery reserve you thought you had plenty of.
That's the part people like you miss out.

Having 20 odd days of theoretical submerged endurance isn't the same thing as having 20 odd days of useful combat endurance.

So no, 11 AIP boats aren't going to own the undersea.

They can make things harder. They'll have endurance. They'll be dangerous.

But endurance on paper doesn't mean much if you don't have the freedom to manoeuvre, evade and fight once the other side starts actively hunting you.

That restraint comes from economic nakedness first and foremost.
Always has and always will.

Then perhaps Pakistan should make genuine peace gesture to India, offer concrete strategic concessions and reduce the size and posture of its military so that New Delhi no longer perceives it as a threat.

Then Pakistan can focus on its economy and human development. No point for the current contradiction and charade then.
